JAMES FLOYD HODGES, OF NEW YORK, N. Y., ASSIGNOR TO THE BUSINESS IMPROVEMENT COMPANY, A CORPORATION OF NEW YORK.

POSITION -IN DICATOR.

To all whom it may concern:

Be it known that I, JAMES FLOYD Honens, a citizen of the United States of America, residing at New York, county of New York, State of New York, have invented certain new and useful Improvements in Position- Indicators, of which the following is a specification.

This invention relates to apparatus for indicating or positioning lines or columns for use in connection with tables, charts or otherswise.

The object of the invention is to provide a novel and sim le apparatus whereby the eye can be quic dy and readily guided to any articular column or line, intersection of co umn or line or other position or location upon a table, chart or other like arrangement of data.

The invention, while particularly applicable to mathematical tables, such as interest tables, wage tables, time tables, railway time cards and the like, is capable of a number of other uses among which may be mentioned line indication in copying manuscript or other matter.

In the drawings which show the invention as appliedwith particular reference to tabulated matter, Figure 1 is a front view, while Fig. 2 is a rear view of the apparatus with the back plate partly broken away showing the mechanism.

In Fig. 1, 1 is the front plate, the apparatus being preferably formed with two plates of any suitable material between which the operating mechanism is held. A is a chart or table applied to the front plate by milled head screws, tacks or otherwise. A sliding rule or straight edge 2 extends across the face of the front plate as shown. By turning a milled head 3 on a shaft 4, extending through the front plate the straight edge 2 may be positioned at any desired height, or brought up to any desired horizontal line or row of figures or other data upon the chart the mechanism for producing the movement being between the front and rear plates.

Referring to Fig. 2, on the shaft 4 is a large pulley wheel 5 having two deep grooves in one of which runs a belt 6 connected around pins 7 and 8 to one end of the straight Specification of Letters Patent.

edge, and in the other a similar but crossed belt 9 connected around pins 10 and 11 with the other end of the straight edge. The retation of the shaft 4 therefore causes the straight edge to move up or down, both ends moving at the same rate.

The construction shown presents distinct advantages. By making the pulley 5 of large diameter a rapid u and down motion of the straight edge can e had.

While I have shown the member 2 as an imperforate rule or straight edge, it is obvious that it may be provided with a slot or opening so that figures or other data may be read through the slot if desired.

The apparatus is of p articular value in connection with tables or charts of many kinds, particularly if the figures are small or the ines closely placed as in the case of railway time cards, wage scales and the like. By suitably positioning such a chart on the front plate the traveling straight edge can be readily adjusted to any particular row or horizontal line of figures or other data and by means of suitable indicating marks carried by or upon the traveling member such information, as for example the time of arrival of a train at a given station or the wage for a fraction of a day, can be ascertained with the greatest ease.

Having described my invention what I claim is:

1. I11 apparatus of the class described, a straight edge, a double grooved pulley, a support therefor, and means for rotating the pulley, a cord around said pulley in one of said grooves connected to one end of said straight edge, and another and crossed cord around said pulley in the other groove and connected to the other end of said straight edge, and means for guiding the cords at points of the same between the pulley and.

the straight edge.

2. In apparatus of the class described, a front and a back plate, a pulley journaled between the two plates, a handle turning with the pulley, a straight edge movable along one of said plates, cords attached to each end of the straight edge, and engaged by said whey, and means between the plates for guic ing the cords.

3. In apparatus of the class described, a

front plate and a rear plate, corner pins 00n- Signed by me at New York this 6th day of niacting saidfplategla straight 1eidge movalolg July 1908, 7 V a on ome sai ates, a 'u ey 'ourna e betvs een said lat s, and aids att aehed to a JAMES FLOYD HODGES' 5 the ends of t e straight edge and running Witnesses:
